Python 如何解决tenserflow安装中由其他版本的软件包引起的错误

我执行了命令

pip install tensorflow

。 但是安装给了我以下错误。下面是日志的一部分

ERROR: After October 2020 you may experience errors when installing or updating packages. This is because pip will change the way that it resolves dependency conflicts.

We recommend you use --use-feature=2020-resolver to test your packages with the new resolver before it becomes the default.

tf-nightly 2.5.0.dev20201102 requires grpcio~=1.32.0, but you'll have grpcio 1.33.2 which is incompatible.
tf-nightly 2.5.0.dev20201102 requires numpy~=1.19.2, but you'll have numpy 1.18.5 which is incompatible.

Ps在执行上述命令之前，我已经卸载了numpy、grpcio、absl py。

卸载

tf nightly

，然后首先卸载

*-nightly

包的其余部分。@hoefling成功了。Thanks@hoefling请你把这个作为回答或投票结束？
